Description

The invention relates to a traffic area, in particular traffic area of a level railroad crossing, which traffic surface laid from each other subsequently, plate-like Eindeckelementen is formed, according to the preamble of claim 1. Such a traffic area is made EP 676 505 A2 known. A similar formation of a traffic area is further out US 5,201,467 A known.

In traffic areas of the aforementioned type usually the plate-like Eindeckelemente together form a continuous gradation-free surface. However, this can often not be met if the substructure, which carries the plate-like Eindeckelemente, not able to give the necessary for a continuous gradation-free course of the traffic area stable support the Eindeckelemente. Vehicles that pass through such a traffic surface, exert on the Eindeckelemente loads whose attack site is constantly changing and migrates from element to element, it being to a depression of the currently loaded Eindeckelemente to a greater or lesser extent compared to the unloaded at that time Eindeckelementen can come. This creates temporarily undesirable gradations of the traffic area at the mutually facing edges of adjacent Eindeckelemente. This in particular, when the Eindeckelemente are elastically mounted, as is the case, for example, with flashing elements, which are elastically supported on the rails of a railway track to form the traffic area of a railroad level crossing. If such rail level crossings are used obliquely to the direction of the track course of heavy road vehicles, the aforementioned adverse effect can occur to a particular degree. But also in other traffic areas formed with plate-like Eindeckelementen, such as those in public places are laid on which plate-like Eindeckelemente, it comes under the influence of usually asymmetrically acting traffic loads to a more or less pronounced vertical movement adjacent arranged Eindeckelemente relative to each other, whereby the aimed at gradations free course of the traffic area is disturbed.

From the above EP 676 505 A2 It is now known to provide at least one recess serving for receiving an alignment bolt recess in at least one adjoining element adjacent to at least one adjacent cover element, said recesses parallel to the surface extension of Eindeckelemente penetrate from the edges thereof in the Eindeckelemente, wherein recesses, which are provided at mutually facing edges of mutually adjacently arranged Eindeckelementen, aligned with each other, wherein the height of the recesses of the height dimension of the alignment bolt in the sense of a leadership of these alignment bolts in the recesses corresponds, the alignment bolts are each mounted adjustably in a recess and by means of an externally operable adjusting means in the form of a flexible wire or the like., Which leads to the respective recess in question, are moved out of the part of the respective alignment bolt recess in part and bridging the gap between adjacent cover elements with a recess of a neighboring cover element which is aligned with the recess located in the respective alignment bolt. The recesses are channel-like, wherein the geometric axes of recesses, which are provided on mutually facing edges of mutually adjacently disposed covering elements, aligned with each other, wherein the alignment bolts are sliding bolt, and wherein the depth of that recess in which the alignment bolt is arranged, at least as long as the length of the respective alignment bar is.

It is an object of the invention to provide a traffic area of the kind mentioned, which is particularly advantageous when heavy loads are to be expected.

This object is achieved with a traffic area having the features of claim 1.

In a structurally simple manner, the occurrence of undesired and disadvantageous gradations in the traffic area - even with heavy loads - counteracted in the present traffic area, and it is also facilitated when laying the Eindeckelemente to achieve a grading gradation of the traffic surface required manipulation and beyond the Get advantage that the compounds, which are provided between adjacent covering elements, can be solved at a later date without further notice, if this should be necessary to carry out conservation work, whereby also single cover elements can be removed from a larger association without further notice. The alignment bolts and their storage in the flashing elements are dimensioned so that they can safely absorb the expected transverse forces, which occur perpendicular to the surface extension of Eindeckelemente and resulting from unbalanced acting traffic loads and transferred to the respective adjacent Eindeckelement, and such a kind of tilting movement Eindeckelemente is counteracted.

According to the invention, it is particularly advantageous if a safeguard against unintentional rotation of the respective toothed wheel is provided. It is also advantageous if a limit stop is provided on each of the slide bolts which delimits the Ausschiebeweg and is preferably formed in the form of a arranged at the inner end of the respective sliding latch plate.

With regard to the formation of the channel-like recesses results in a structurally simple embodiment, which is favorable in many cases, also with regard to the male loads, if it is provided that the channel-like recesses are formed in the form of blind holes.

A variant of this, which often offers advantages with regard to the production of the flashing elements, is characterized in that the flashing elements have two mutually parallel edges on which channel-like recesses are provided, the channel-like recesses extending continuously from one of these edges to the other.

Both in terms of manufacturing and especially with regard to the absorption of the loads which act on the Eindeckelemente from the outside, it is advantageous if it is provided that the channel-like recesses are lined with pipes.

A design which allows easy access to the installation of the Eindeckelemente and in a possible removal of the same from the association actuated components is characterized in that gears are provided, each on a perpendicular to the surface extension of the Eindeckelemente in this outward sitting leading wave. A variant of this, which is characterized in that gears are provided, each sitting on a plane parallel to the surface extension of Eindeckelemente in this outward-leading wave, it allows in many cases, e.g. in the formation of the traffic area of a railroad level crossing, in which between the two rails of a track a single row of Eindeckelementen is laid to achieve a closed surface at the top of the Eindeckelemente. With regard to the formation of the gears and with regard to the insertion of these gears in the Eindeckelemente for engaging in the toothing of the sliding bolt designed as a dead bolt, it is advantageous if it is provided that the teeth of the gears are formed in the form of a toothing introduced into the outward leading shaft ,

Fig. 1 shows an embodiment of an inventively designed traffic area 1, which forms the traffic area of a railroad level crossing. It is this traffic area of plate-like Eindeckelementen 3a, 3b formed, which are subsequently laid between the rails 2 of a track and supported on these rails. Preferably, one sees between the rails facing the edges of the Eindeckelemente and the rails elastic inserts, which are not shown in the drawing, before. As in Fig. 1 is schematically indicated, it is also outside of the rails 2 then laid down Eindeckelemente 3c, which are the same or similar to the Eindeckelemente 3a, 3b are executed.

In the individual coverslip elements 3a, 3b recesses 7a, 7b are provided at the edges 4a, 4b, which serve to receive alignment bolts, which are designed in the form of sliding latch 5. For each individual alignment bolt, a pair of recesses 7a, 7b is provided, which are adjacent to each other on mutually facing edges 4a, 4b arranged Eindeckelemente are provided, said recesses 7a, 7b penetrate parallel to the surface extension of Eindeckelemente 3a, 3b of the edges 4a, 4b in the Eindeckelemente. The recesses 7a, 7b are, corresponding to the formation of the alignment bolt in the form of sliding bars 5, channel-like and align the geometric axes 10a, 10b of recesses 7a, 7b, which on mutually facing edges 4a, 4b of mutually adjacently arranged Eindeckelementen 3a, 3b are provided and face each other, with each other. The sliding bolt 5 have a cross section which results in a sliding fit in the channel-like recesses 7a, 7b. In this case, in particular, the height H of the recesses 7a, 7b corresponds to the height dimension of the locking bolt designed as a sliding bolt 5. The recesses 7a have a depth 14 which is at least as large as the length of the slide bolt 5 designed as a locking bolt and it remains this alignment bolt inserted into the recesses 7a until the installation of Eindeckelemente is performed. Thereafter, the alignment bolts are moved out of the recesses 7a over part of their length, bridging the separation 9 present between adjacent covering elements, each with a respective recess 7a aligned recess 7b of a neighboring Eindeckelementes come into engagement. To induce this movement of the sliding latch 5, these sliding latch on a running in its longitudinal direction toothing 11 and gears 12 are provided which can be placed with the toothing 11 for the longitudinal displacement of the sliding bolt designed as a locking bolt into engagement. These gears 12 are arranged to be rotatable in the opening provided for the respective alignment bolt channel-like recess 7a. Each of these gears 12 is seated on an outwardly leading adjusting shaft 8a, which in the in Fig. 1 illustrated embodiment is perpendicular to the surface extension of Eindeckelemente. Said longitudinal displacement of the sliding latch 5 is indicated by an arrow 13. A structurally simple and robust embodiment of the gears, which also requires relatively little force for moving the sliding bolt 5, is obtained by forming the teeth of the gears in the form of a toothing incorporated in the adjusting shaft. Preferably, a limit stop 15 is also provided on the sliding bolt 5, which limits the Ausschiebeweg. Such a limit stop can be realized, for example, in the form of a plate provided at the inner end of the respective sliding latch which, upon reaching the maximum intended push-out length of the sliding latch, engages the respective gear wheel 12 and inhibits its further rotation. It is also advantageous to provide a safeguard against unintentional rotation of the respective gear. Such a backup can be performed, for example, in the form of a pin or strap which can be inserted into the toothing.

At the outer end of the adjusting shaft 8a preferably approach surfaces are provided for turning tools, which are to be set for the rotation of the gears 12 to the adjusting shafts 8a. It may be a simple slot 18 for inserting a screwdriver or even a three-, four- or hexagonal shape at the end of the adjusting shaft 8a, wherein such shapes are executed on the outer surface of the adjusting or in the form of a depression in the same can.

By the engagement of the sliding bolt 5 in the recesses 7a, 7b, which are provided opposite one another and flush with each other in adjacent flashing elements, said sliding bars bridging the separation present between adjacent flashing elements, transverse forces which arise due to uneven loading of the flashing elements and seek to alter the height position of the individual flashing elements are received in a stabilizing manner and the undesirable emergence of gradations in the traffic area is counteracted. Such unbalanced loads of considerable size may occur, for example, at level crossings, which are often passed by very heavy road vehicles, and in particular when the direction of travel F is not perpendicular to the longitudinal direction G of a track but, as in Fig. 1 indicated, obliquely to it runs.

At the in Fig. 1 illustrated embodiment, the channel-like recesses 7a, 7b are designed in the form of blind holes, such type these recesses occupy only a small part of the total cross section of the Eindeckelemente. Such recesses can be easily molded into the flashing members in the manufacture thereof.

In order to achieve a precisely shaped inner surface of the recesses with relatively little effort in the manufacture of Eindeckelemente, it is advantageous to the channel-like recesses 7a, 7b with tubes 16 line, as shown in Fig. 4 to 7b is shown. With regard to a simplification of the molding of the channel-like recesses in the Eindeckelemente and with regard to achieving a precisely aligned course of such recesses, it is often also favorable if it is provided that the channel-like recesses extend continuously from one edge 4a of a Eindeckelementes to the other edge 4b, such as this in Fig. 5 is shown. In such an embodiment, the provision of a lining tube 16 is particularly advantageous, such a tube 16 not only facilitates the molding of the recesses, but also can provide an advantageous contribution to the strength of Eindeckelemente.

According to the embodiment Fig. 5 sits in the toothing 11 of a sliding latch 5 engaging gear 12 on a parallel for the surface extension of the relevant Eindeckelementes in this outwardly leading shaft 8b, whereby the upper side of the respective Eindeckelemente may be formed closed, and an inadvertent penetration of foreign material along the waves leading outward from the gears is counteracted.

In the in the FIGS. 6 to 8 illustrated traffic surface are provided to secure a continuous gradation-free course of the successively laid plate-like Eindeckelementen 3a, 3b traffic area 1 wing-like pivot bolt 6, as in principle already made US 2 509 558 are known. This pivot bolt 6 are each mounted on a shaft 8a, which extends through a recess 7c perpendicular to the surface extension of the respective Eindeckelementes. By rotating the shaft, the pivot bolt 6 with a part of its length from the recess 7 c, in which this pivot bolt is mounted, moved out and inserted into the aligned with the recess 7 c recess 7 d, as indicated by the arrow 17. The height H of the recesses 7c, 7d corresponds to the height dimension of the pivot bolt 6 and it is counteracted such a kind the emergence of a relative vertical displacement between the subsequently laid Eindeckelementen 3a, 3b. The recesses 7c, 7d are formed pivoting angle limiting with respect to the pivot bolt 6, in that these recesses have end faces 7c ', 7d' to which the pivot bolt 6 engaging in the recess 7d comes to rest.

Fig. 9 shows in plan view a traffic area, which is formed from plate-shaped Eindeckelementen, which are two-dimensional consecutively laid. At the mutually facing edges 4a, 4b adjoining each other subsequently laid Eindeckelemente 3a, 3b alignment bolts are arranged, as shown in the FIGS. 7 and 8 are shown.

Fig. 10 shows a variant of this, are provided in the alignment bolt, as in the in Fig. 1 illustrated embodiment.

At the in Fig. 1 illustrated embodiment, the Covering elements 3a, 3b, two mutually parallel edges 4a, 4b, wherein at each of these edges two recesses are provided for receiving Verriegelungsriegeln. The distance that the recesses provided on such an edge have from one another is equal to the distance that the recesses provided at the other edge have from one another. It is aligned in each case one provided on an edge 4a of a Eindeckelementes 3b recess with a recess provided on the other edge 4b of Eindeckelementes, wherein at one edge bearings for alignment bolt-forming recesses 7a are provided and at the other edge recesses 7b, in each case from a stored Recess 7a projecting alignment bolt comes into engagement. It requires this embodiment, a continuous same positioning of the individual Eindeckelemente that together form the traffic area. In modification for this purpose, only one recess or even more than two recesses can be provided on each of the two mutually parallel edges of the Eindeckelemente.

A variant of the embodiment according to Fig. 1 is in Fig. 11 illustrated, this variant requires no provision for maintaining a certain orientation of the individual mounting elements when joining to the traffic area. There are mutually offset on each of the edges 4a, 4b of the respective Eindeckelementes 3a, 3b both a bearing recess 7a and provided for engagement recess 7b provided, wherein, moreover, with regard to the escape and the mutual distances of the recesses 7a, 7b Same conditions as in the embodiment according to Fig. 1 available.
